Let  ${\mathrm{C}}_{\mathrm{NaCl}}$ and ${\mathrm{C}}_{{\mathrm{BaSO}}_4}$ be the conductance (in S) measured for saturated aqueous solutions of NaCl and ${\mathrm{BaSO}}_4$ , respectively, at a temperature T.

          Which of the following is false ?

Here, NaCl is strong electrolyte so it ions completely at room temperature. So its ionisation no changes (V-U less extent charge) with increase of temperature. But ${\mathrm{BaSO}}_4$ is weak electrolyte and hence its conductance increases with temperature.
